Mesh Analysis

    [SOLVED] Mesh Analysis

    1. The problem statement, all variables and given/known data

    I am having trouble solving this circuit for its currents. I have also tried nodal analysis, and haven't been able to come up with anything

    2. Relevant equations



    3. The attempt at a solution

    Can anyone check what's wrong with my mesh equations? I skipped the mesh with the independent voltage source (1A) and because I wasn't sure how to form a supernode with it. But I have enough equations to solve, but when I do I get the wrong answers.

    Your current source isn't equal to i3 - i4.

    Thanks for your reply, you're right i messed that equation
    1 A = i3 + i4 ? right
    Unfortunately, I still seem to be getting an incorrect answer (but they are very close to the correct answers) is there anything else I messed up? I forgot to draw the direction of ix on the picture but it is the current between v2 and v1 (thru the 5 ohm resistor). And I believe I did get the current correct on that one.

    i3 is simply equal to 1 amp. There is no need for a loop equation for Loop(i3). This also makes the problem easier to solve.
